Subject: Transferring files over tftp
Date: Thu, 15 Nov 2018 16:24:18 +0100 [thread overview]
Message-ID: <1542295458.2675.12.camel@phytec.de> (raw)
Hello,
I am facing tftp issues when trying to transfer files > 2GB. This ends up in a crash:
barebox@Phytec phyCORE AM335x:/ cp /mnt/tftp/2GB_plus_1M .
eth0: 100Mbps full duplex link detected

Copying a file <2GB works even without timeouts.
Causing this seems to be commit:
commit e3e55fa3aa698bb92fa4362a36e102749c13c124

fs: tftp: improve file size handling
Previously we used FILE_SIZE_STREAM unconditionally. Instead, fill the
inode size with a valid filesize if we have one and only if not fall
back to FILE_SIZE_STREAM.
Reverting the commit reveals a second issue. After 2GB the transfer breaks up silently.
Maybe some overflow? Any idea where to look at this further?
Thanks,
Teresa
